I am retired and my wife is dead. (The opening two sentences give an account of Benjamin's past, and suggest that the main thread of the movie revolves around Benjamin's work and love, which will be something that the senior population of an aging country will have to deal with, and that most parents in China solve by square dancing, matchmaking, and shopping on Taobao.)
Instead, Benjamin chooses to play golf, read books, watch movies, play cards, yoga, cook and garden, and even learn a little Chinese. (You can see that Ben is a person who is still curious about the world and continues to expand the width of his limited life)

Ben is a good observer, humble, humorous, and open to learning, and does not take the disadvantage of age as an excuse, but uses his experience to make up for the lack of learning ability as much as possible.
